EDUCA O DE ADULTOS – OS CURSOS DE FORMA O PROFISSIONALIZANTE: UMA ALTERNATIVA PARA O EXERCíCIO GLOBAL DE CIDADANIA
Ivone Tambeli Schimdt,Wilson Roberto Lussari
Nuances : Estudos sobre Educa??o , 2010,
Abstract: Este trabalho é resultado da reflex o conjunta de seus autores em rela o às práticas pedagógicas adotadas para a Educa o de Adultos em cursos profissionalizantes – e à importancia dos conteúdos programáticos na forma o do indivíduo. Um dos desafios da atualidade é a forma o do cidad o comprometido com o trabalho e a ética, aliados à competência. Os cursos profissionalizantes exercem importante papel nessa forma o, n o só pela aquisi o e/ou amplia o de conhecimentos específicos como também oferece subsídios para melhor integrá-lo na sociedade. é indispensável ao indivíduo apropriar-se dos recursos e meios disponíveis no mercado aliados às novas tecnologias, para conferir-lhe um novo perfil de profissional sem, contudo, desprezar os fins educacionais que contribuem para o crescimento da pessoa. Cidadania n o acontece, n o é algo pronto, mas uma constru o permanente do indivíduo, adquirindo novas posturas para viver em sociedade.
Líquens da reserva biológica do Alto da Serra de Paranapiacaba
Pereira, Wilson Roberto;Marcelli, Marcelo Pinto;
Acta Botanica Brasilica , 1989, DOI: 10.1590/S0102-33061989000300008
Abstract: the biological reserve of the serra de paranapiacaba is part of the serra do mar at santo andré city, s?o paulo state, brazil (23o4ts, 46o19'w, 800m above sea level). it is covered with a tropical rain forest and is the most rainy place of brazil. it stands near (16km) of cubat?o city (at sea level) from were receives a great deal of air pollutants. the principal aim of this work is verify the old and recent lichen floras of the reserve. altogether 63 species were found. the most (16) of the 25 species held at the sp herbarium (instituto de botanica de s?o paulo) could not be collected in 1988 and nowadays 60% of the lichens are parmelia s.l. species. no stictaceae or corticolous fruticose species, wliich are present at the herbarium, could be recollected in 1988. air pollution, too high umidity and shade can together be the responsible for the flora poorness.
Técnica hidrop?nica para triagem de genótipos de tomateiro quanto à eficiência de absor??o de fósforo
Silva, Ernani Clarete da;Maluf, Wilson Roberto;
Horticultura Brasileira , 2012, DOI: 10.1590/S0102-05362012000200022
Abstract: phosphorus (p) is the most limiting nutrient to plant growth and development in acidic soils of tropical and subtropical regions. the objective of this study was to establish a nutrient solution (hydroponics) technique for screening of tomato genotypes for efficiency of phosphorus absorption. an area of 160 m2 within a protective structure covered with 150 micron polyethylene film was used, with masonry-built channels 20 cm wide x 15 cm in height spaced 0.80 m apart. the experimental setup was a split plot design with factorial treatments and four replications. plots comprised two concentrations of p in nutrient solution (0.50 and 60 ppm), whereas subplots comprised two tomato genotypes with contrasting p absorption efficiencies [pi 121665 (efficient, crt/crt) and tom-598 (crt+/crt+)]. after this test, the two genotypes were again grown in a completely randomized experimental design with four replications, under the same structure, under concentration of 0.20 ppm p in nutrient solution. we evaluated the fresh mass of aboveground part, dry mass of aboveground part, fresh mass of root, dry mass of root and length, area and volume from the root. the hydroponic technique was effective to screen tomato genotypes for resistance or tolerance to phosphorus deficiency. the concentration of 0.50 ppm p in nutrient solution in nft hydroponic system was suitable for this purpose.
Surface characterization of alumina reinforced with niobium carbide obtained by polymer precursor
Acchar, Wilson;Silva, José Roberto Bezerra da;
Materials Research , 2006, DOI: 10.1590/S1516-14392006000300005
Abstract: active filler controlled pyrolysis of polymers (afcop) is a recent method for obtaining near-net shaped ceramic bodies. alumina based composites have been developed for use as cutting tools, so knowledge of the surface composition is extremely important because it is directly related to the hardness and wear resistance samples containing a fixed concentration of 60 wt. (%) of polysiloxane and a mixture of metallic niobium and alumina powder were homogenized, uniaxially warm pressed at 80 °c and subsequently pyrolyzed in flowing argon at 1200, 1400 and 1500 °c. analysis of the surface composition was carried out by x ray photoelectron spectroscopy, infrared spectroscopy, x ray diffraction and scanning electron microscopy. the results have indicated that the formation of the phases on the surface depends strongly on the niobium/carbon ratio in the raw materials.

Blay, Alberto;Tunchel, Samy;Sendyk, Wilson Roberto;
Pesquisa Odontológica Brasileira , 2003, DOI: 10.1590/S1517-74912003000300007
Abstract: the use of autogenous bone grafts is considered to be the best choice for reconstructive surgery. in the periodontal literature, the utilization of osseous coagulum was suggested by the end of the sixties. the purpose of this study is to consider the use of bone collectors (bone traps) as an alternative method for obtaining material to fill small bone imperfections, such as fenestrations and dehiscences. thirty samples were obtained from bone drilling during fixture installation in patients (13 men and 17 women, with an average age of 54 years) requiring treatment at the department of periodontology and implant dentistry, university of santo amaro. these samples were fixed in 10% neutral formaldehyde for 24 hours and subjected to histological preparation, in order to evaluate the presence of viable osteoblasts. in addition, the material was placed in a fluid thioglycolate medium and incubated for 24 hours at 36 ± 1°c in aerobiosis and anaerobiosis. bacterial growth evaluation was made by using six different culture media (macconkey agar, blood agar base, mannitol salt agar, anaerokit ltd medium, anaerokit ltd - bile medium, anaerinsol). the results show that, if proper care is taken to prevent saliva contamination during the surgical procedure, this method of collecting autogenous bone may be useful in situations where small amounts of bone are required.
